SELF-FILLING FOUN TAIN -PEN specification of Letters Patent.

Patented Jan. 30, 191 '7.

To all whom 'it may concern: f

Be it known that I, MORRIS SHEMIN, a citizen of the United States of America, residing at Bayonne, Hudson county, New Jersey, have invented a new and useful Self- Filling Fountain-Pen, of which the follow.- ing is a specification.

My invention relates to fountain pens and particularly to an improvement in a socalled self-filling pen.

My object is to provide certain novel and useful features of construction whereby the with the end of the barrel l, in this instance by a sliding plug 4.

5 represents a collapsible sack closed at the rear end, the front end being connected to the plug 4. The usual ink duct 2tl leads from the sack A5 to the pen 2 through the stopper 3 and plug 4.

6 is a bar preferably of resilient material which lies alongside the sack 5 and within the barrel 1. The rear end of the bar 6 is suitably shaped to be secured friction-tight within the barrel back of the sack whereby the bar may be given a relatively fixed or operative position.

7 is a cam pivoted at one end in one end of a slot 8 in the barrel, said pivotal connection being preferably located about midway in the length of the bar 6 and sack 5. The cam 7 may be formed by a curved bar of a suitable size to pass through the slot 8 when swung from the position shown in Fig. 1 to that shown 'in Fig. 2. The free end of the cam 7 is provided with a suitable head or shoulder 9 which snaps into an opening in the barrel 1, after the manner of a ball and socket fastening.

10 is a stop which limits the inward movement of the free end of the cam, that is to say, when the stop rests against the outer side of the barrel 1, as shown in Fig. 1, the cam 7` is in its inoperative position. The

stop 10 thereforecoperates with the headed end of the bar 6 so as to assist in holding the cam in its inoperative position, shown 'in Fig. l. Should it be desired to fill the pen, the free end of the cam 7 is disengaged from the barrel 1, and the said cam is swung around until the curved portion passesv through the slot 8 to cause the collapse 'of the sack 5 through the medium of the bar (3, as shown in Fig. 2. This collapse of the sack eXpels the air so that if the pen is dipped into a bottle of ink; as indicated in Fig. 2, the sack willfbe filled or partially filled with ink that will be drawn by suction up through the ink passage to the pen when the cani is released and the sack tends to assume its normal expanded form, shown in Fig. 1. If the sack is not sufficiently filled, the position of the pen may be reversed so that the pen proper will stand uppermost, whereupon the sack may again be compressed, this time only partially, and only suflicient to expel the remaining air therefrom, so that by again dipping the penpoint into a supply of ink andreleasing the cam, more ink may be drawn into the sack.

11 `is a plug at the rear end of the barrel 1 which may be removed to permit the removal of the bar 6 if for any reason that is desirable.

12 is the usual. can.

Vhat I claim is:

In a fountain pen of the self filling variety, a barrel having a longitudinal slot in one side wall and intermediate the length thereof, a removable pen carrying plug at one end of said'barrel said plug having an ink duct therethrough, a collapsible sack carried by said plug, the interior of said sack being in communication with said duct, a

yielding bar within said barrel along side of said sack and underneath said slot, an operating member comprising a curved lever pivoted at one of itsends in'said slot, said MORRIS SHEMIN. s
